Abstract

Abstract : We devised a threshold voltage compensation pixel circuit using back‐gate bias voltage. Variations in threshold voltage can be reduced to 10% while improving the saturation characteristics of a driving transistor. We fabricated a 5.29‐in Quad‐VGA OLED display using this pixel circuit.
